78° on Nov. 16, 1999, the hottest reading for this week of the year since 1989. Next is 77° in 1989.
Aguilar’s center stands about 6,400 ft above sea level. Within three miles the land runs from 6,220 ft to 7,210 ft, a difference of 990 ft: steep hill country. The highest named summit within 15 miles is East Spanish Peak, about 12,630 ft, 15 miles west.
Under the town center the state geologic map shows Pierre Shale, undivided, from the Late Cretaceous, 66 to 100 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 7×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 8 mi of the line.
Conglomerate, sandstone, shale. Age: Paleocene, 56 to 66 million years old. About 5 mi of the line.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 4 mi of the line.
Sandstone, shale. Age: Eocene, 34 to 56 million years old. About 4 mi of the line.
Arkose, siltstone, shale. Age: Late Cretaceous to Paleocene, 56 to 100 million years old. About 3 mi of the line.
Shale, sandstone. Age: Late Cretaceous, 66 to 100 million years old. About 0.4 mi of the line.

A raindrop that lands in Aguilar reaches the Gulf of America by way of the Apishapa, the Arkansas and the Mississippi: about 1,910 river miles.
Lakes on the way: Murray Lake and Ozark Lake.
920 miles of the trip are on the Arkansas.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Aguilar; river miles along the main stem, rounded.
Aguilar has a warm-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 15° in January. A normal year brings about 48 inches of snow; with the rain, that comes to about 17 inches of water.
On November 14 Aguilar normally reaches 56° and falls to 24°. The record high is 77°, in 2007; the record low 0°, in 2014. The most rain on this date, 0.56 in, fell in 1993.
Normals 1991–2020 and records since 1989 at Trinidad Lake, 18 miles south-southeast. NOAA, through RCC-ACIS.
